이동통신시스템에 있어서 이동국과 기지국간에 동기를 맞추기 위한 주파수 운용방법에 관한 것이다.A frequency operation method for synchronizing between a mobile station and a base station in a mobile communication system.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

초기동기를 맞추기 위하여 기존에는 전 주파수 밴드(band)에 걸쳐서 스캐닝(full scanning)하는 방식을 사용했지만, 이러한 방법을 사용할 경우 광대역 밴드로의 전 주파수 스캐닝으로 인한 초기 동기를 맞추는데 있어서 너무 많은 리던던시(redundancy)를 초래하여 시간적 손실이 우려되었으므로 이를 해결하기 위한 방법을 제공한다.Previously, full scanning was used to match initial synchronization. However, this method uses too much redundancy in initial synchronization due to full frequency scanning to the wideband. ), So we are concerned about the time loss and provide a way to solve it.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

이동통신시스템의 이동국과 기지국간에 초기 동기를 맞추는 데 소요되는 시간을 최소화한 본 주파수 운용방법은, 현재 망을 이루고 있는 기지국에서 사용하고 있는 초기 동기용 주파수의 주기를 나타내는 인덱스정보를 입력하는 과정과, 메모리로부터 초기 동기용 주파수를 읽는 과정과, 도약패턴 다항식을 이용한 초기 동기용 도약 주파수를 발생하는 과정과, 초기동기 도약 주기를 결정하는 과정과, 시작동기신호를 발생하는 과정과, 소정시간의 타임 아웃을 세팅하는 과정과, 상기 소정 시간의 타임 아웃 세팅 후 동기 비트를 디스에이블하는 과정과, 상기 과정들의 수행 도중에 일정 시간 간격으로 타이머 인터럽트를 발생하여 동기 여부를 체크하는 과정으로 이루어짐을 특징으로 한다.This frequency operation method minimizes the time required for initial synchronization between a mobile station and a base station in a mobile communication system. The method includes inputting index information indicating a period of an initial synchronization frequency used by a base station in a network. Reading the initial synchronization frequency from the memory, generating an initial synchronization hopping frequency using the hop pattern polynomial, determining an initial synchronization hopping period, generating a start synchronization signal, Setting a timeout, disabling the sync bit after setting the predetermined timeout, and generating a timer interrupt at a predetermined time interval during the execution of the processes to check for synchronization. do.
